DESCRIPTION
The PCM1690-Q1 is a high-performance, single-chip,
24-bit, eight-channel, audio digital-to-analog converter
(DAC) with differential outputs. The eight-channel,
24-bit DAC employs an enhanced, multi-level
delta-sigma (ΔΣ) modulator and supports 8-kHz to
192-kHz sampling rates and a 16-/20-/24-/32-bit width
digital audio input word on the audio interface. The
audio interface of the PCM1690-Q1 supports the
time-division-multiplexed (TDM) format in addition to
the standard I2S, left-justified, right-justified, and DSP
formats.
The PCM1690-Q1 can be controlled through a
three-wire, SPI-compatible interface, or two-wire,
I2C-compatible serial interface in software, which
provides access to all functions including digital
attenuation, soft mute, de-emphasis, and so forth.
Also, hardware control mode provides a subset of
user-programmable functions through two control
pins. The PCM1690-Q1 is available in a 12-mm ×
8-mm (12-mm × 6-mm body) HTSSOP-48 package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
